These Phillips flat-head machine screws are designed for precision assembly in electronics, appliances, industrial equipment, and general hardware projects. With a clean, low-profile flat head and a standard cross recess drive, they sit flush with the surface, reducing snag hazards and providing a professional finish. Available in a range of sizes from M2 to M4, these screws are manufactured to consistent tolerances, making them a reliable choice for both professional workshops and DIY repairs.
| Size | Thread Diameter D (mm) | Head Diameter S (mm) | Head Height K (mm) |

Note: The thread length (L) varies by option. Please select your required length from the dropdown menu. Manufacturing tolerances apply to all dimensions.
The "M" stands for metric, and the number refers to the outer thread diameter in millimeters. For example, an M3 screw has a thread diameter of approximately 3mm. This is a standardized international measurement system used for most modern hardware.
These screws are manufactured from standard steel or stainless steel (depending on the specific variant you select). They are designed for general indoor use in dry environments. If you need corrosion resistance for outdoor applications, please check our stainless steel product line.
A flat head screw is designed to sit flush with the surface in a countersunk hole, creating a smooth, flat profile. A pan head screw has a cylindrical head that sits on top of the surface. Flat head screws are preferred for applications where a clean, flush finish is required or where you want to avoid a protruding head.
Yes, these screws feature a standard Phillips cross drive. They can be driven with any standard Phillips screwdriver or a power tool fitted with a Phillips bit. Use a properly sized bit to avoid stripping the drive recess.
Measure the thickness of the materials you are fastening together. The thread length (L) should be long enough to pass completely through the material you are attaching and engage fully with a nut or into a tapped hole. Add at least 2-3 mm of thread engagement to ensure a secure hold.
